The condition of existing residential buildings with a sliding support in the foundation in the city of Bishkek

Abstract

This article is devoted to the analysis of the current state of residential buildings with a sliding support in the foundation, in the city of Bishkek. The residential buildings under consideration were built at different times, according to different designs and different structural and planning schemes with seismic protection systems. As you know, with sliding supports, it is possible to significantly reduce the horizontal loads transmitted to the bearing above-ground structures of the building if it is possible for them to slip relative to the foundation. A detailed analysis and review of these existing residential buildings with a seismic-isolating sliding belt in the foundation using various structural and planning schemes and materials has been performed. The constructed experimental residential buildings with seismic protection systems, according to the results of the work performed, it is recommended to use sources of energy absorbers, consisting of rubbing surfaces of steel, fluoroplastic and a layer of bulk material placed between them.
